Sorry Oz, but that just shows the flaws in the bill of rights making owning a firearm a right.
If it was something we were all born with and we all had an equal understanding of what they are capable of, then I could see justification for it being a right......
but both you and I know the world is full of idiots. We can all learn how to diddle our wangs.... we can all learn how to make our own decisions and opinions..... but I kinda think a training course in firearms being manditory would be a good thing.
Technically in order to protect what I think is a misinterpretation of the constitution, one could still own/posses a firearm as they see as their right to do so...... but until they get a license or take a safety course, they are not allowed to use them legally
